''Mycobacterium vanbaalenii'' is a rapidly growing mycobacterium that can use polycyclic aromatic hydrocarbons. It was first isolated from petroleum-contaminated estuarine sediments and has been shown by 16S rRNA gene sequencing to be closely related to Mycobacterium aurum and Mycobacterium vaccae. ''M. vanbaalenii'' has potential use in the bioremediation of polycyclic aromatic hydrocarbon contaminated environmental sites. Etymology: vanbaalenii of Van Baalen, in memory of Dr Chase Van Baalen, late Professor at The University of Texas Marine Science Institute, Port Aransas Marine Laboratory, Port Aransas, TX, USA. ==Description== Microscopy * Gram-positive, acid-fast rods (1.4 um long and 0.7 um wide) Colony characteristics *Colonies are smooth and saffron yellow. Physiology *Can grow well at 24 and 37 °C, with minimal or no growth at 42 °C. *Classified as a rapidly growing Mycobacterium species *Cells are aerobic, Catalase- and urease-positive, reduce nitrate to nitrite. *metabolizes salicylic acid, hydrolyses Tween 80, reduces tellurite and uses pyrene, anthracene, fluoranthene, naphthalene, phenanthrene, 1-nitropyrene, 6-nitrochrysene, 3-methylcholanthene and benzopyrene. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mycobacterium vanbaalenii」の詳細全文を読む スポンサード リンク
